Este trabalho enfoca os aspectos críticos da fiscalização sanitária das cargas de produtos farmacêuticos nas áreas sob a jurisdição da Gerência de Portos, Aeroportos e Fronteiras (GGPAF) da Agência Nacional de Vigilância Sanitária (ANVISA), durante os processos de desembaraço, na importação ou exportação. Para o alcance dos resultados pretendidos, procedeu-se à análise da legislação sanitária vigente, reuniram-se os dados comerciais de importações e exportações, seguindo-se uma avaliação dos documentos da ANVISA e dos relatos fornecidos pelas Coordenações de diversas Unidades de PAF, sobre inspeções físicas das cargas, bem como dos locais de armazenagem das mesmas. A partir destes dados foi elaborado um roteiro de inspeção, validado através de sua aplicação in loco em Terminais Alfandegados. Obteve-se um diagnóstico dos riscos sanitários aos quais estavam submetidos os produtos farmacêuticos, particularmente nas etapas de transporte e armazenamento temporários em áreas aduaneiras, nas quais a responsabilidade sobre o produto não está bem definida. Este documento permitiu comparar os Regulamentos sanitários disponíveis com as práticas dos técnicos envolvidos na fiscalização dessas áreas, constatando-se altas discrepâncias. Diante disso, concluiu-se pela necessidade de harmonização das ações, dos saberes e das informações originadas de cada Unidade Administrativa de PAF. No intuito de colaborar com a consecução desse propósito, esta dissertação apresentou propostas de padronização dos procedimentos de controle sanitário, voltadas a orientar melhores práticas que conduzam à minimização dos riscos associados à atividade em foco.

Os depósitos sem vencimento formam grande parte da base de captação das instituições financeiras. Esses passivos, depósitos à vista ou de poupança, embora permitam que seus titulares saquem a qualquer momento o montante integral de suas aplicações, permanecem nas instituições financeiras por longos períodos de tempo. A falta de maturidade contratual definida torna o gerenciamento de riscos desses produtos uma difícil tarefa. Este estudo busca analisar as maturidades implícitas dos depósitos de poupança através de um modelo de carteira replicante. Como resultado, são apresentadas estruturas para alocação de fluxos de caixa para gestão de risco de mercado e liquidez dos depósitos de poupança.

Este estudo, por meio de uma pesquisa exploratória, descritiva e explicativa, buscou identificar os riscos associados ao processo de mudança na implantação de um novo modelo de gestão de operações denominado gerenciamento integrado de operações (GIOp), considerando novos processos e tecnologias na área de negócio de E&P da Petrobras. Utilizando como referência o modelo proposto por Kotter (1996), no qual identifica oito passos para a gestão de mudança em uma organização, e com base na aplicação do questionário proposto por Cohen (2005) denominado “The Change Readiness Assessment”, que permite aferir dentro dos oito passos onde estão localizados potenciais riscos e ameaças, este estudo apresenta reflexões sobre as percepções de quatro categorias de trabalho (executivos, gerentes, técnicos e equipe de projeto) da UO-ES, e de que forma impactam na prontidão para a mudança. O estudo trata também da importância do papel fundamental desempenhado por líderes neste processo, que asseguram o patrocínio necessário para a sustentabilidade do projeto. O resultado dos questionários demonstra uma percepção de risco considerável em todas as categorias. O único passo que não foi abrangido na área de risco é o senso de urgência (passo 1), que apresentou baixo risco. Como a mudança não se sustenta somente no passo 1, é importante que se reúnam os indivíduos, no sentido de buscar desenvolver uma avaliação compartilhada das questões relativas ao processo de mudança (problemas, oportunidades) entre os grupos envolvidos, objetivando um clima de confiança e de comunicação acerca do projeto, para assegurar que os resultados sejam atingidos. Nesse contexto, o sentido de urgência serve como força motriz para acelerar e dinamizar os passos seguintes.

Esse estudo busca analisar os impactos causados pelo Ciclo Monetário, o Ciclo Econômico, o Nível da Indústria e a Condição do Mercado de Ações nas variáveis do CAPM para portfólios de ações de diferentes setores da indústria no Brasil. O banco de dados utilizado compreende séries temporais mensais, do retorno de ações de 17 setores da economia, no período de Janeiro de 2008 à Dezembro de 2014. Foi observado que existem relações estatisticamente relevantes entre variáveis macroeconômicas e o excesso de retorno dos portfólios de ações analisados. Além disso, foi possível notar que essas relações tem efeitos distintos sobre os riscos sistemáticos e idiossincráticos dos portfólios. A maior parte dos resultados obtidos não se mostraram estatisticamente relevantes, o que sugere que existem outras variáveis explicativas que se relacionam com as variáveis dependentes de forma mais robusta, assim como já apontado pela literatura existente, no caso do Brasil. No entanto, foi possível observar que há efeitos indiretos das variáveis macroeconômicas sobre o retorno dos ativos através do canal de retorno do mercado.

Os depósitos sem vencimento são uma importante fonte de funding das instituições financeiras, e apresentam um desafio na gestão dos riscos de juros e liquidez, por não apresentarem um vencimento definido. Os depositantes podem sacar o montante de suas aplicações, bem como aportar novos volumes, a qualquer tempo sem a incidência de penalidades. Atualmente não há um modelo regulatório padronizado para mensurar o risco de juros desses produtos, bem como seu requerimento de capital. No entanto, novas regulamentações tem surgido com o intuito de, dentre outras coisas, trazer certa padronização para a modelagem dos depósitos sem vencimento, aumentando a comparabilidade do perfil de risco entre instituições financeiras. Essas regulamentações aumentam a necessidade de modelos quantitativos que definam um perfil de run-off da carteira ou de evolução dessa carteira no tempo. Este estudo tem como objetivo propor uma abordagem para modelar os fluxos de caixa esperados dos depósitos de poupança que possibilitará calcular o risco de mercado e apresentar sua aplicação dentro das novas normas de requerimento de capital que estão sendo propostas. Como resultado calculamos o risco de mercado e requerimento de capital para um balanço teórico.

The Brazil is the third largest producer of cashew nuts in the world. Despite the social and economic importance of the cashew nut, its production is still carried out artisanally. One of the main problems encountered in the cashew production chain are the conditions under which the roasting of the nut occurs to obtain the kernel from the shell. In the present study was conducted a biomonitoring of the genotoxic and cytotoxicity effects associated with the elements from the cashew nut roasting in João Câmara - RN, semi-arid region of Brazil. To assess the genotoxic was used the bioassay of micronucleus (MN) in Tradescantia pallida. In addition, it was performed a comparative between the Tradescantia pallida and KU-20 and other biomarkers of DNA damage, such as the nucleoplasmic bridges (NBP) and nuclear fragments (NF) were quantified. The levels of particulate matter (PM1.0, PM2.5, PM10) and black carbon (BC) were also measured and the inorganic chemical composition of the PM2.5 collected was determined using X-ray fluorescence spectrometry analysis and the assessment of the cytotoxicity by MTT assay and exclusion method by trypan blue. . For this purpose, were chosen: the Amarelão community where the roasting occurs and the Santa Luzia farm an area without influence of this process. The mean value of PM2.5 (Jan 2124.2 μg/m3; May 1022.2 μg/m3; Sep 1291.9 μg/m3) and BC (Jan 363.6 μg/m3; May 70.0 μg/m3; Sep 69.4 μg/m3) as well as the concentration of the elements Al, Si, P, S, Cl, K, Ca, Ti, Cr, Mn, Fe, Ni, Cu, Zn, Se, Br and Pb obtained at Amarelão was significantly higher than at Santa Luzia farm. The genotoxicity tests with T. pallida indicated a significant increase in the number of MN, NBP and NF and it was found a negative correlation between the frequency of these biomarkers and the rainfall. The concentrations of 200 μg/mL and 400 μg/mL of PM2.5 were cytotoxic to MRC-5 cells. All together, the results indicated genotoxicity and citotoxicity for the community of Amarelão, and the high rates of PM2.5 considered a potential contributor to this effect, mainly by the high presence of transition metals, especially Fe, Ni, Cu, Cr and Zn, these elements have the potential to cause DNA damage. Other nuclear alterations, such as the NPBs and NFs may be used as effective biomarkers of DNA damage in tetrads of Tradescantia pallida. The results of this study enabled the identification of a serious occupational problem. Accordingly, preventative measures and better practices should be adopted to improve both the activity and the quality of life of the population. These measures are of fundamental importance for the sustainable development of this activity.

The new oil reservoirs discoveries in onshore and ultra deep water offshore fields and complex trajectories require the optimization of procedures to reduce the stops operation during the well drilling, especially because the platforms and equipment high cost, and risks which are inherent to the operation. Among the most important aspects stands out the drilling fluids project and their behavior against different situations that may occur during the process. By means of sedimentation experiments, a correlation has been validated to determe the sedimentation particles velocity in variable viscosity fluids over time, applying the correction due to effective viscosity that is a shear rate and time function. The viscosity evolution over time was obtained by carrying out rheologic tests using a fixed shear rate, small enough to not interfere in the fluid gelling process. With the sedimentation particles velocity and the fluid viscosity over time equations an iterative procedure was proposed to determine the particles displacement over time. These equations were implemented in a case study to simulate the cuttings sedimentation generated in the oil well drilling during stops operation, especially in the connections and tripping, allowing the drilling fluid project in order to maintain the cuttings in suspension, avoiding risks, such as stuck pipe and in more drastic conditions, the loss of the well

The relation between metabolic demand and maximal oxygen consumption during exercise have been investigated in different areas of knowledge. In the health field, the determination of maximal oxygen consumption (VO2max) is considered a method to classify the level of physical fitness or the risk of cardiocirculatory diseases. The accuracy to obtain data provides a better evaluation of functional responses and allows a reduction in the error margin at the moment of risk classification, as well as, at the moment of determination of aerobic exercise work load. In Brasil, the use of respirometry associated to ergometric test became an opition in the cardiorespiratory evaluation. This equipment allows predictions concerning the oxyredutase process, making it possible to identify physiological responses to physical effort as the respiratory threshold. This thesis focused in the development of mathematical models developed by multiple regression validated by the stepwise method, aiming to predict the VO2max based on respiratory responses to physical effort. The sample was composed of a ramdom sample of 181 healthy individuals, men and women, that were randomized to two groups: regression group and cross validation group (GV). The voluntiars were submitted to a incremental treadmill test; objetiving to determinate of the second respiratory threshold (LVII) and the Peak VO2max. Using the método forward addition method 11 models of VO2max prediction in trendmill were developded. No significative differences were found between the VO2max meansured and the predicted by models when they were compared using ANOVA One-Way and the Post Hoc test of Turkey. We concluded that the developed mathematical models allow a prediction of the VO2max of healthy young individuals based on the LVII

Tamoxifen (TX), a drug used in the treatment of breast cancer, may cause hepatic changes in some patients. The consequences of its use on the liver tissues of rats with or without diabetes mellitus (DM) have not been fully explored. The purpose of this multidisciplinary study was to evaluate the correlation between plasma hepatic enzyme levels and the presence of iron overload in the hepatic tissue of female Wistar rats with or without streptozotocin-induced DM and using TX. Female rats were studied in control groups: C-0 (non-drug users), C-V (sorbitol vehicle only) and C-TX (using TX). DM (diabetic non-drug users) and DM-TX (diabetics using TX) were the test groups. Sixty days after induced DM, blood samples were collected for glucose, alanine aminotransferase (ALT), aspartate aminotransferase (AST) alkaline phosphatase (ALP) and bilirubin measures. Hepatic fragments were processed and stained with hematoxylin and eosin (H&E), Masson s trichrome, Perls. The hepatic iron content was quantified by atomic absorption spectrometry. AST, ALT and ALP levels were significantly elevated in the DM and DM-TX groups, with unchanged bilirubin levels. Liver iron overload using Perls stain and atomic absorption spectrometry were observed exclusively in groups C-TX and DM-TX. There was positive correlation between AST, ALT and ALP levels and microscopic hepatic siderosis intensity in group DM-TX. In conclusion, TX administration is associated with liver siderosis in diabetic and non-diabetic rats. In addition, TX induced liver iron overload with unaltered hepatic function in 2 non-diabetic rats and may be a useful tool for investigating the biological control of iron metabolism

Objective: The purpose of this study was to investigate the kinetics of this micronutrient in schoolchildren between the ages of 6 and 9 years, of both sexes, and to verify its sensitivity in detecting alterations in body zinc status. Methods: Nutritional assessment was performed by body mass index. Food intake, venous zinc tolerance test and zinc kinetics were carried out before and after 3-month oral zinc supplementation. Results: Of the 42 children studied, 76.2% had healthy weight. Only energy, calcium and fiber intake were suboptimal before and after oral zinc supplementation. Serum zinc and total-body zinc clearance, although at normal levels, increased significantly after zinc supplementation. Conclusion: We concluded, therefore, that kinetics is a sensitive tool for detecting changes in body zinc status, even in children without a deficiency of this mineral. Furthermore, kinetics showed a positive response to supplementation and may be a sensitive parameter to evaluate the efficacy of this therapy

The aim of the present study was to assess the effectiveness and adverse effects on dental enamel caused by nightguard vital bleaching with 10% carbamide peroxide. This was accomplished through the interaction of researchers from different areas such as dentistry, materials engineering and physics. Fifty volunteers took part in the doubleblind randomized controlled clinical trial. They were allocated to an experimental group that used Opalescence PF 10% (OPA) and a control group that used a placebo gel (PLA). Fragments of human dental enamel from the vestibular surface of healthy premolars, extracted for orthodontic reasons, were fixed to the vestibular surface of the first upper molars of the volunteers for in situ observation. Bleaching was performed at night for 21 days. The observation periods included Baseline (BL), T0 (21 days), T30 (30 days after treatment) and T180 (180 days after treatment, only for the OPA group). Tooth color was assessed by comparing it with the Vita® scale and by the degree of satisfaction expressed by the volunteer. We also assessed adverse clinical effects, dental sensitivity and gingival bleeding. The study of adverse effects on enamel was conducted in vivo and in situ, using the DIAGNOdent® laser fluorescence device to detect mineral loss. Scanning electron microscopy (SEM) was used to check for superficial morphological alterations, energy dispersive spectrophotometry (EDS) to semiquantitatively assess chemical composition using the Ca/P ratio, and the x-ray diffraction (XRD) technique to observe alterations in enamel microstructure. The results showed that nightguard vital bleaching with 10% carbamide peroxide was effective in 96% of the cases, versus 8% for the PLA group. Dental sensitivity was present in 36% (9/25) of the cases. There was no significant association between gingival bleeding and the type of gel used (p = 1.00). In vivo laser fluorescence analysis showed no difference in values for the control group, whereas in the OPA group there was a statistically significant difference between baseline values in relation to the subsequent periods (p<0.01), with lower mean values for post-bleaching times. There was a significant difference between the groups for times T0 and T30. Micrographic analysis showed no enamel surface alterations related to the treatment performed. No significant alteration in Ca/P ratio was observed in the OPA group (p = 0.624) or in the PLA group (p = 0.462) for each of the observation periods, nor between the groups studied (p=0.102). The XRD pattern for both groups showed the presence of three-phase Hydroxyapatite according to JCPDS files (9-0432[Ca5(PO4)3(OH)], 18-0303[Ca3(PO4)2.xH2O] and 25-0166[Ca5(PO4)3(OH, Cl, F)]). No other peak associated to other phases was found, independent of the group analyzed, which reveals there was no disappearance, nucleation or phase transformation. Neither was there any alteration in peak pattern location. With the methodology and protocol used in this study, nightguard vital bleaching with 10% carbamide peroxide proved to be an effective and safe procedure for dental enamel
